OF SAID WILLIAM DBAFT-RIGGING.

I specification of Letters Patent. Application and Kay 2a, 1908. Serial no. samba- Pa'tented May '7 1912.

To all whom it may concern:

Be it known that I, WILLIAM P. Barranoonr, a citizen of the United States, and a resident of Davenport, in the countyof Scott and State of- Iowa, have invented certain new; and useful Improvements in Draft- Riggings, of,which' the following is a clear, full, and exact description.

My invention relates to draft-rig ing, which is particularly applicable to ra' way cars, the underframes of which comprise a single I-beam center-sill.

The object of my invention is to support the draft-rigging in a suitable opening in the ends of a single rolled beam of the center-sill, in such manner that the strain of the stress and pull can be communicated to said center-sill in such manner that said strain is communicated to all parts of the same.

A further object is to provide an integral column connecting the web of the bifurcated ends of the single center-sill, above and below the draft-rigging, through which the pulling strain of the draft-rigging is communicated to the underframe of the car. And a further object is to separate the forward part of the draft-rigging from the part in which the sprin are housed and to to give it an in e- .ndent longitudinal movement extending it forward of the aforesaid web column. And a still further object is to'connect the rear portions of the draw-bar with the housing for the springs, by links, the forward ends of which are constructed to permit of a limited butting movement of the draw-bar of the car-coupler before receiving the bufiing impact and communicating the same directly to said housing. This I accom lish by the means hereinafter fully descri ed and as particularly pointed out in the claims.

In the drawings: Figure 1 shows a broken away end portion of a single center-sill, having its extremity secured to the end-sill of the car and having my improvements applied thereto. Fig. 2 is a longitudinal horizontal section taken on dotted line 2-2, Fig. 1. Fig. 3 is a transverse section taken on dotted line 33, Fig. 2. Fig. 4 is a peredge spective view of the rear broken away end of the draw-bar, drawn to a, slightly larger scale. Fig. 5 is a perspective view of the butting-block.

In the drawings A represents a single I-beam center-sill, the ends of which are provided with bifurcations a, a', the uppermost of which is secured, by means of suitable corner castings b, to the end-sill B of the car. This end-sill'is shown to be constructed of a channel-beam theflanges of which project inward, and itis provided, in the vertical plane of the couplln C, with a cast metal frame 0, that surroun s the o jening through which said coupler extends. e lower horizontal portion of said frame 0 is flan d rearwardly, at about the oente'rof-wi tn thereof to form a seat d, u on which the lower flange of the lower rests, and is secured byrivets or otherwise.

Coupling 0 extends longitudinally. back ifurcations a" into the longitudinally elongated slot or.

space a separating the bifurcations a, a, and its rear end terminates near the crotch of'the same. This crotclris formed by a vertical column D, consisting" of an integral portion of the web of-the. center-sill, and reinforcing plates e riveted to .eachside thereof, and it constitutes the dividing medium between the'longitudinally extendmg opening E in which parts of the draft-rigging are located and the space between said b1f11 1- cations or and a. Opening E is, preferably, in alinementwith and is greater in height than s ace a,-and the vertical edge of the web 0 the center-sill formin its rear end is reinforced and strengthene by means of peculiarly shaped cast-plates F, which are riveted thereto, substantially as shown. The ofthese plates in the same transverse plane as the adjacent end of opening E is verticaL-whereas the opposite edge, pre erably, describes a semi-circle, and the entire outer edgesv of said plates-are flanged laterally, substantially as shown. The rear portion of the edges of'the space a between the bifurcations and the upperand lower edges of opening E are reinforced by a U-shaped angle-iron strip G, the end of which farthest from'the coupler is bent and extends around 't'urngagends .of brackets 5,

v marshes "are a1 the rear semi-circular end of reinforcing plates These binding strips G, are of such sizieftliat th'eln'lateral flanges project to the shine extent as flanges H of said reinforcingpl'ates and-the upper and lower edgesfof thereinforcing-plates e of column D areflanged outward and riveted to the horizontal flanges of said binding-strip. As thus constructed the openings in the single arolled metal am constituting the centersill,,"for insects iron of'the draft-rigging, do not Weakenthe end of saidcenter-sill, but addto its strength, and its ability to receive 1 and'resist the stress of the pulling and pushg. o edr' z er gg gr j ,Q'Ihe; draft-rigging comprises a housing-2 for the springs 3, that consists of a tubular casing whose-, rearg tend 4 is closed and nor. jmall yib ars against the forward flanged end '20 f hereinforcing plates H, and whose other .isjopen;..- Thishousing is placed in open- -E,*a'nd 'retained'therein by the upi that are secured-- ets aor' boltsto the vertical flanges of I gle iron binding strips, below open- The length of housing 2 is less than opening li ands its forward end does not 'yreach; -:o:lu' n IZD, and 'in'the space between 'said coluinn 'and' the housing, a buflingblock'tijis placed,- :that consists of truncated cone-shaped casing, i jend'is solidg and which, in front of this rear "solidportion;is provided with a' vertigil slot-7,. thatzextnds to and through its forward endi ='l his -slot- 7 is of sutfiient width toenable the forward portions of the resulting divisions offthe blockto pass forward on each 'side' of column D.

A short disteueerrom its rear end the sides of the coupler are -pre tied with laterally projecti'ng'bosses 9 j a ainst which the forward extremities" of extensions -8 normally imping, andsaii'dcoupler'is provided with a transverse-opening which strikes through bosses 9 5211111; forins 'a seat for a transverse key-1'0; whose ends project beyond the-outer v surface-ioflsai'd bosses asuitablevdistance. illie' vertical"'sides"of the housing 2, preferabl yiin ih'" i horizontal pl'aneQas key a flanged whose rear I so" enlarged and" provided with. a horizontally elongated opening 13, corresponding in height to thethickness, l

but greater in length than the width of the key, the ends of which extend through said openings. 7 v

The springs 3 are located in the rear portion of the housing 2, and have their rear ends bear against the closed end, 4, of the same. The forward ends of said springs, however, bear forward against a followerplate 14, within said housing the normal position of which is in a transverse plane slightly forward of the center of trunnions 11. The rear end of the bufler-block 6 communicates its movement to said followerplate by means of one or more eccentrically journaled rolling members 15, the construction of which it is unnecessary to dwell on as they constitute part of a well known type of draft rigging now extensively in use.

In operation, when a pushing motion is imparted to the coupler it moves to the rear independently of the links 12 for a. short and, through the medium of the buffer-block and the rolling members 15-, 15, slightly compresses the springs 3, which latter neutralize the shock and impart the strain through the rear end of opening E to-the center-sill until the ends of the key come in contact with the rear end of elongated openings'13 of the links 12, Whereupon the bufling strain is imparted direct to the housing of the springs'and, through it to. the center-sill. When the draw-bar is subjected to a pulling strain, the key 10, through the medium of links 12 draws the housing forward and compresses springs 3 against the follower-plate 14, members 15, the buffing-block 6, and the column D, until the limit of the forward compression of the springs is reached, or until said springs compress sufficient to resist the pulling strain. Thus it will be seen that the pulling strain is imparted to theccnter-sill and, through it, to the underframe of the car, through the medium of the colmn D, and the bufling or pushing strain, which is much greater than the pulling strain, isv imparted to the center-sill through the rear end of opening Eand' the plates reinforcing the same to the center-sill.
